Amyloid-beta metabolism in age-related neurocardiovascular diseases

Area of Science:

• Neurocardiovascular Medicine
• Aging Research
• Vascular Biology

Background:

• Shared risk factors link cardiovascular and cerebrovascular diseases, including stroke and Alzheimer's.
• Endothelial dysfunction and blood-brain barrier compromise are implicated in age-related diseases.
• Imbalances in amyloid-beta (Aβ) peptide metabolism may connect neurocardiovascular conditions.

Purpose of the Study:

• To review the role of amyloid-beta (Aβ) as a potential link between age-related neurocardiovascular diseases.
• To explore the effects of various interventions on Aβ metabolism across different body tissues and fluids.
• To discuss clinical implications, knowledge gaps, and future research directions for Aβ in neurocardiovascular health.

Main Methods:

• Narrative review of existing epidemiological and scientific literature.
• Analysis of studies investigating Aβ metabolism in the brain, cerebrospinal fluid, blood, and vascular tissues.
• Examination of how genetic factors, age, lifestyle, and therapeutic interventions influence Aβ levels.

Main Results:

• Aβ metabolism dysregulation is associated with cardio- and cerebrovascular diseases.
• Interventions targeting Aβ can modulate its levels in the brain, blood, and peripheral tissues.
• Aβ modulation impacts brain, vascular, and cardiac health, suggesting a unifying mechanism.

Conclusions:

• Amyloid-beta (Aβ) peptide represents a potential common pathway in age-related neurocardiovascular diseases.
• Targeting Aβ metabolism offers therapeutic possibilities for conditions like stroke, Alzheimer's, and heart disease.
• Further research is needed to translate these findings into effective clinical strategies for neurocardiovascular health.
